Hey. I have a problem. my X1 cannot charge via USB rather the contrary. I had it at 70% battery on my notebook. After about 10 minutes, I wanted to remove it and it was nothing more to it. I.e. there came the warning 5% ...
Why is that? How can I recharge it?

Have you checked the "Charge via USB" in the phone's energy saving settings?
If yes, you can look how much currency the USB port provides when the phone is plugged in. To do so you go to the device manager (on your notebook) and look for the right USB-Root-Hub. Select the properties and check for the value that is shown in "power settings". The USB-port should provide 500mA.
ye... everything is correct. what else can it be? :-\\
could be a process sucking power out faster than USB can put it in?
Is the battery cover warm?
try a soft reset first and plug it in again
my problem is X1 can only charge on usb port with computer.
it doesnt charge when i plug in ac/wall charger or car charger, i just shipped X1 for repair!
This morning I almost got a shock because my X1 stayed black and seemed to be totally dead. Luckily I soon figured out that the Battery was empty, no currrent left on it to let the device even blink. But what happened? When I went to bed yesterday I connected it to the USB cable and left it charging! Everything seemed the same as all the times before. What may have caused this?
Only things that were diffrent from my usual charging procedure:
The Cable were connected to the PC USB Slot.
I shut the PC (laptop in this case) down but the USB Slots had still power. The charging lights of my X1 followed their normal pattern.
Normally I unplug the power cable from PC to prevent the USB Slots to have power. Because my USB harddisk keeps rotating while having power from the USB.
Normally I charge the X1 directly from the power outlet. X1 turned off.
So this time PC was off. X1 was off. USB Slots still got power. X1 connected with USB Slot. X1 seemed to charge normally.
Well, the result was that my X1's Battery was totally empty the next morning. Obviously instead of charging the USB slot drained of the whole battery power! But note that the charging lights were active as normal and the Battery was still warm in the morning.
Perhaps this helps others to prevent such issues.
you are crazy if you:
1. charges from laptop
2. from powered OFF device
you can repeat this case endless - xperia will be drained

Don't charge it in standby mode, how stupid is that?
What? I don't see any reason not to charge it from a laptop. Even if it's powered off, as long as the USB ports have power (mine has a BIOS setting for this) there is nothing wrong with that.
Also, what does it matter if you're charging the phone powered off or powered on?
On an interesting note, however, the same thing actually happened to me last night.
I plugged the phone into the wall socket to charge it (battery was at about 20%) and I actually saw the battery percentage rise as I was still using the phone. I turned it on in the morning (from standby, not powered off), and as soon as I pulled the power cable it went dead as the battery was completely empty.
I have no idea what might have caused this, and it hasn't happened to me before.
Next time dont power off ur X1,
if same happends then your battery is suffed.

1) This was accidently
2) Why? I dont like it when mobile phones are on standby while I'm asleep. Charging the device when powerd off should make absolute no difference? Worked everytime but the one where it was connected to a powered of laptop.
Why will the Xperia been drained?

What does this BIOS setting say? I assume that my USB slots had too less power when laptop is off. But its very strange that your Device got drained while connected to the wall socket and in Standby mode. Maybe my USB slots were not the cause? Weird ...

It is weird. Since your phone was off I don't think it would use any of its battery power.
I have a ThinkPad, and IIRC the BIOS setting is something like "Always On USB", in the USB settings. With this turned on the laptop will power its USB ports even when turned off, as long as the laptop itself has the power cable connected.

from powered off PC, when power on usb enough to wakeup PC or feed LEDs,
but not to charge another device. in that case power go into the weaker side, means from x1 -> pc
I had this problem too... seems after hard resetting my phone one time, one option was different to normal after I hard reset,
Click on the battery icon at the top of the screen
Theres a tick box, that says:
"When device is turned on, do not charge the battery when connected to the PC."
this was ticked for some reason. Unticked it, and all was fine.
Try it
I noticed this happened to me too for the first time, after i put in the wall charger and the the phone seemed to charge, i found it completely dead after 3 hours and the battery was warm, running a vanilla R1A

Also I think for the X1 to charge- it requires activesync. from my experience, when connected to the pc- without activesync, the X1 would indicate charging- but never actually gets charges. Hence when your notebook is off, activesync obviously wouldn't be running-> no charge either.

I assume a turned off PC would only power its USB port power pins and wouldn't respond to any transmissions on the data pins. So to the phone it should look just the same as if it were connected to the wall charger (just probably with a bit less power).
Also, when I have my phone connected to my laptop through USB Internet Sharing it does actually charge (it doesn't connect to ActiveSync when using Internet Sharing).
The device should charge in any USB mode as the USB port's power pins supply power regardless of the protocol used on the data interface.
Does the X1 have no safety feature that does prevent the battery from being drained?
In my case I assumed it happened because of the USB Port had too less power. But when you turn off your PC (+USB power) and let the X1 connected it would still mean a movement of current from the X1 Battery --> inside the PC as long as they are not on the same potential. If the PC is earthed somewhere (for example connected to the wall socket) the Battery would be drained out totally! They never get to the same potential as long the Battery has power.
As jjm34 mentioned, if the PC is on and USB slots powered normally the X1 should charge in any case.
Maybe this is not the real cause of the problem. People are reporting that the X1 got drained while connected to the wall charger! That's really weird. How can the battery being drained by this? Any suggestions @Ethermind ?

It could be:
It's drawing power FROM your x1 to provide power for laptop internal components.

Mine has. Put it on the wall charger and the charging symbol is there. It reaches 100%, the charging symbol disappears and it shows 100. Then in the morning it's at 90% even though it was still on the wall charger.
I've not left it plugged into a 'running' pc or laptop long enough to see if the phone runs off the battery after it's reached 100%, but it shows the same symptoms. Charging symbol until 100%, then it changes to 100%, no more charging symbol.
Even MSVC stops reporting '% & charging', just reports the % level once it's reached 100%.
I made 2 observations :
It seems the X1 need usb data pins active to charge the battery. The wall plug has something enabled to give power to the data pins (by the way, the wall plug can charge an iPod or an iPhone, it works perfectly). I tried using a cheap wall plug bought in china, no way to charge the X1 or my iPod as there was no power on the data pins. So when connected to an off PC, I'm not sure what's happening. If someone can give a try to analyze this with a multimeter, that would be nice.
It seems also the X1 stop charging after going to 100 %, and won't charge anymore unless you unplug - replug it.
Thanks for your contribution.
Maybe there exists a real hardware failure.
Normally the X1 should charge until the Battery reaches the 100% level. Then there has to be a switch that prevents the Battery from getting overloaded which is good. So charging stops.
The switch blocks charging until you unplug the device once it has reached the full battery level. Thats ok, too. You should not loose much Battery after a full charge and with a device on standby or powered off. And it prevents the Battery getting reloaded at high percentages. Otherwise it would start charging at 99% and stop again at 100 and so on, all the time.
But now assume the switch has sometimes, somehow a failure.
Instead of preventing current to get inside the battery it enables that current can flow into the wall charger.
I do not expect that the current flows into the power outlet. Maybe it gets "lost" in the current transformer that you've plugged into the power outlet (Thats the one you plugged the USB cable in.). Lost means it simply gets warm / hot.
Measuring the current with a Multimeter would be a nice proof. If someone has the technical knowledge and qualification to disassemble the current transformer and the USB cable, you have the go .
I haven't tested it, but I doubt the current flows back into the charger, or back into the USB port on a laptop / pc.
But how does the Battery discharge then? When there is no current flowing out it will stay loaded. (it goes like d(q)/dt+div(j)=0 )
Did you all charge your phone while it is on (standby)? I noticed the same problem when I charged my x1 while it is standby. When I pull the plug from my laptop (I used my laptop for charging, laptop powered on), I get 90% battery life. It seems like there is a switch to cut out the power input if the battery reaches 100% and power the phone from the battery.
Try to charge your phone while it is off. I did it yesterday, and it had stopped charging even before I unplug it from wall output, and I got 100% battery life.
Btw, this is not confirmed yet... it is just based on my experience...
Hi, I'm wondering if there's any software out there that disable charging of the Diamond when the usb cable is plugged in. The reason is for protecting the battery from frequent charging and discharging, which I believe isn't good for the battery.
Thanks.
Maybe I'm completely mistaken, but there's an option for that when you click on the battery symbol. I'm not on an english ROM, but it reads something like "do not charge when connected via USB".
Settings -> System -> Power
Check "When device is turned on, do not charge the battery when connected to the PC"
yes, but frequent charging is not going to do any harm to your battery
I have noticed that when TD2 is on external power (USB cable computer connected) the battery continues to drain.
I have activated the option "When device is turned on, do not charge the battery when connected to the PC".
I have done this in order to avoid partial charging. My phone is new and the manual says: "Some batteries perform best after several full charge/discharge cycles."
So, when connected to PC, the battery does not charge, but wasn't supposed that the phone rely on external power? The battery keeps draining.
Is this normal?
Shouldn't it be like on laptops? When connected to an outlet the device relies on external power, and when plugged off, the battery takes over.

this is not only for your computer but also for any external power sourches

You can't rely on a computer USB to give enough power for operation of the phone under all conditions, so it has to use its battery. Some USBs on laptops and "netbooks" only give 500mA max. If the phone were to even briefly try and draw more than this, the USB would cut the power off.
A USB mains adapter is different, as it's usually capable of 1000mA or more. I believe HTC phones "test" the supply and adapt their charging strategy accordingly.
Sorry - double posted
The draining happened without operating the phone.
No background processes.
It just reduced the backlight, and the baterry was losing charge as time went by.
Your best bet then is to deactivate ""When device is turned on, do not charge the battery when connected to the PC" again.
I think HTC gives this option for the reason I outlined above (to enable you to connect it to netbooks etc without the USB switching off, like it does with some external hard drives which take too much power).
I wouldn't worry too much about "partial charging" because it shouldn't damage or reduce the life of a lithium ion battery. Just do a full discharge/ charge cycle perhaps every month, to recalibrate the battery metering.
This message:
"When phone is on, do not charge the battery when connected to a PC"
makes no sense to me, because as soon as I connect my HD2 to my computer, it immediately begins to charge, and I do not know any way to stop it from doing so.
What harm can this cause?
The message itself seems contradictory. Why would someone connect their HD2 to the computer when it was off? To charge it?
nah it means that it could be charged only from usb charger (not PC) either when its on or off... when your phone is off it cant be charged through PC because it wont make connection and i think this function is made when u often connect and disconnect your phone from PC so u dont damage your battery...

Okay, but if that is true, then why does the phone ALWAYS charge when connected to a PC if the frequent connection/disconnection could harm the battery?
The warning message is characteristically cryptic in true MS fashion.
Why not just state directly: "Your charges via USB, but disconnecting it frequently while charging could damage your battery" if that is what they meant?
Where did you see this??

In the Active Sync dialogue when you connect the HD2 to a computer.
While connected using the usb cable you can press at the bar and then battery and you'll see the option. I'm also wondering if this will cause any harm to the battery.

It won't.
This option makes sense mostly when you connect the mobile to a laptop running on battery, for tethering for example. Instead of draining the laptop's battery and end with a full one on the mobile, ticking the little box means that both batteries will drain at the same time.

No, a PC in standby usually has power on the USB voltage lines, even when it's turned off.
This is indeed an option to prevent the phone from trying to charge itself from the USB connection. This could be useful for laptops or other devices (such as portable media players with USB host capabilities) where power must be saved instead of being used to charge the phone.
hi guys, does this explain the new O2 ROM 1.72 NOW not charging the phone when connected to my PC? Or is it a new bug I have found.
It does charge via the power socket/adapter but not through the PC...any thoughts?

Thanks for clearing that up!
There a number of points to make.
Connecting and disconnecting your phone will do no harm at all.
Some USB ports will struggle to start the charge process when the battery is very low.
If the phone is connected and being used in some way at the same time (if WiFi or bluetooth its on then there will be a continuous drain which a USB port may not be able to accommodate and it will appear as if the PC/laptop is sucking the power out of the battery.
The same thing can happen on a low battery and this is then very bad as the phone will operate at or around the discharge cutoff point and that will ruin the cell.
So you have the option to turn it off if there its any evidence of these situations occurring.
